"That's right!" , Chu Yanlin seemed to be smiling because he heard the correct answer.

Chu Yu: .....

**Next**

Early in the morning, Chu Yu had breakfast, read a few medical books, and then went out with Shuangqi.

She promised to go to see the mother and son in the suburbs again today.

Chu Yu, who came out of the general's mansion, first went to the pharmacy and bought a lot of medicinal materials, and then walked in the direction of the wooden house in the suburbs.

"Miss, we go in and out of the General's Mansion so frequently, I'm afraid we will be targeted by someone with a heart." , Frost Seven looked around and said lightly.

Chu Yu looked behind him and said, "I'm afraid that these people have been staring at us for a long time." ”

"It's okay, it's up to them what they want to do." , Chu Yu said lightly, and did not take these people to heart.

But.....

"Let's get these people around first, don't let them come with them to the outskirts." , Chu Yu said in a low voice.

What she was afraid of was that the two mothers and sons would get into some unnecessary trouble because of her.

"Yes." , Frost Seven nodded.

Then the two of them walked in the direction of the crowded street.

After turning around, Chu Yu walked in the direction of the crowd, and after a while, he threw off those "tails".

They had been delayed for a while on the way to get rid of the men, and by the time they reached the hut in the suburbs, it was already sunset, the fog had already been dispelled by the sun, and the dew had already evaporated.

Chu Yu looked at the medicine bag in his hand, and then looked at the sky, and couldn't help frowning, after all, he missed the best time to decoct the medicine.

I haven't had time to collect the dew today, and I'm afraid the effect of this medicine will not be as good as expected.

As soon as Shuangqi opened the fence door, Huan'er ran out of the house when she heard the sound.

Seeing that it was Shuangqi and Chu Yu, he said anxiously, "Sister, hurry up and save my mother." ”

Chu Yu hurriedly walked into the house after hearing this.

There was a faint smell of blood rust in the room, and it was Huan'er's mother who vomited blood.

Chu Yu didn't say a word, so he grabbed the woman's hand and took the pulse.

The situation is not good.

"Auntie, are you angry?" , Chu Yu asked with a frown.

The eldest mother was originally a pleural pneumocratic, her heart and lungs were not good, and she was angry, which aggravated her condition even more....

The eldest lady said weakly, "I couldn't help but be angry with Huan'er last night, this kid is too unteachable, let me worry." ”

"Auntie, you are weak now, and the most taboo thing is to work hard, and this mood ups and downs is even more taboo." , Chu Yu sighed and said.

"Huan'er will never make her mother angry again." , Huan'er wiped her tears and said.

"Okay, okay." , The eldest lady smiled when she heard this, but the smile seemed to be very difficult.

"Shuangqi, Huan'er, you go and fry these medicines, just fry a pack, boil for an hour, and boil the water into a small bowl." , Chu Yu picked up the medicinal herbs that had just been placed on the ground.

"Okay." Frost Seven nodded, got up and looked at the woman meaningfully.

Suddenly, only the eldest lady and Chu Yu were left in the wooden house.

Chu Yu took out a sachet embroidered with lotus leaf patterns from his arms.

The wormwood and orange peel in the sachet are all dried.

Chu Yu opened the sachet, took out some orange peel and wormwood from it, and sprinkled these things under the eldest mother's bed.

"What is this?" , The eldest lady looked at Chu Yu's movements with a curious expression.

Chu Yu put those things in place and explained, "Wormwood can repel mosquitoes, and orange peel can remove the smell." ”

The smell of blood in this room was too strong for her to like.

The eldest lady laughed weakly, "I see, I'm tired of the girl." ”

Chu Yu shook his head and said that it was not troublesome.

"Auntie, you lie down and rest first, I'll go and see the medicine, let them decoction the medicine, I'm a little worried after all."

The eldest lady nodded weakly.

Looking at Chu Yu's departing figure, the eldest lady showed a trace of entanglement on her face, she helped them like this, but she had never told her about their origins.

However, in case.... Their identities are revealed, and they will never recover... She didn't dare to take the risk, and she didn't want the two girls to be involved in these things.

Then let the secret follow her. They've been in this place long enough, and it looks like they're going to have to change places... It's just that the poison in her...

A hint of determination flashed in the eldest lady's eyes.

The girl didn't seem to say her identity, but judging by her dress, she seemed to be an official lady. She really can't bear to involve such a kind two girls....

.....

Outside the door, Shuangqi was about to put the clay pot on top of the stone mill, while Huan'er lit the flint and piled up the firewood.

Chu Yu looked at the scene in front of him, and he had an unprecedented feeling of warmth.

Chu Yu shook his head, put aside this strange thought, and strode forward.

"I'll see." , Chu Yu lifted the lid of the crockpot.

Hearing Chu Yu's voice, Shuang Qi consciously flashed to the side, in these aspects, she was not as good as Miss.

"Well, exactly." , the water in the crockpot is moderate.

"Huan'er, let me come." , Chu Yu squatted down and took the firewood from Huan'er's hand.

Huan'er flashed aside obediently.

"Sister..."

"Call me Sister Yu." Chu Yu's faint voice came.

When Shuangqi heard Miss correct her name like this, it became clear in her heart that Miss's identity should not be exposed.

"Sister Yu, my mother kisses her...", Huan'er's voice whimpered in the middle of speaking.

Chu Yu piled up the firewood, then got up and said softly, "As long as you don't get angry with her and give your mother medicine on time every day, you will be fine." ”

"Really?" , Huan'er didn't seem to believe it.

"Hmm." , Chu Yu nodded.

At first, when she diagnosed her, she thought that she was overworked and caused by liver fatigue and aging, but she thought about it last night and read some medical books before she realized that this may not be due to overwork, but because of long-term depression.

In that case, it's a little easier.

However, the symptoms of the eldest lady seem to be quite similar to a poison, which seems to be called a hundred days deep....

However, Hundred Days Deep usually only appears in palace fights, and it seems unlikely that this lady will be poisoned by this kind of poison.....

"Huan'er, what's your last name?" , Chu Yu asked curiously.

Unexpectedly, Huan'er heard this, but did not answer her, but ran to the house.

Chu Yu looked at the direction he was leaving, his eyes deepened.

It's not easy for this kid to hide secrets.

Chu Yu was not annoyed, and lowered his head to control the firewood.

But how did she end up with this?

Chu Yu, who had stopped, finally had time, and she couldn't help but think of this question.

Why did she suddenly have to meddle with her own affairs? Or for someone who doesn't even want to tell her the truth, her real name....

"Sister Yu, my mother asked you to come in." Just as Chu Yu was thinking, Huan'er suddenly ran out and shouted.

Chu Yu put down the pu fan in his hand, handed it to Shuangqi, and got up and walked into the inner room.

As soon as I opened the door, I saw the eldest lady and said with a grateful face, "Miss Yu, your great kindness to our mother and son, we will never forget." ”

The eldest lady moved, paused, and said, "Although I only know you for a while, the eldest lady can see that you are a kind woman." ”

"But just now, I still wanted to hide our identity from you, and now that I think about it, I'm really a little ashamed."

"In fact, my time is short, and it is in vain to take those medicines, I have been poisoned, a hundred days deep, this poison is fierce, and ordinary doctors will not have an antidote."

It seems that because she said too much in one breath, the eldest mother coughed again.

Seeing the eldest lady coughing, Huan'er immediately stepped forward and patted her on the back.

"Auntie, don't worry, you speak slowly." , Chu Yu also said softly.

It turned out to be a hundred days deep!

She finally remembered.

Master has talked about this kind of poison, this kind of poison is extremely bad, people who take this poison, ordinary diagnosis can not be diagnosed at all, if there is no cure within 100 days, the body will be worse day by day, and finally the whole body organ will fail and die, and when you die, it is the time of taking the poison for 100 days.

Hence the name 100 days deep.

When she was studying medicine before, she was quite interested in these hundred days, so she studied a lot carefully....

If you want to ask her why she is so interested in Hyakini, it has to start with the events of her previous life.

Because she was afraid of the deep palace battle in her previous life, in this life, she carefully studied all the poisons that could be used in the court, so that if she married into the royal family again, she would not be ignorant of some poisons, and people would be quietly framed.

In fact, Chu Yu is not only interested in Bairishen, she is interested in all poisons.

But after studying for so long and a hundred days, she didn't diagnose the poison of a hundred days, which is really a secret, and it really shouldn't be .....

The symptoms of this 100-day poison are somewhat similar to the symptoms of organ damage caused by general overwork, and this 100-day poison is not an ordinary poison, and ordinary people have no chance to come into contact with it, so at the beginning, Chu Yu felt that the eldest lady should not have the opportunity to come into contact with this poison, and it was her illusion that caused her to misdiagnose.

Now that I know the truth, I look at it again, and the symptoms of this aunt are actually not much different from those of the hundred days deep.

Immediately, Chu Yu remembered that this lady's hands didn't seem to be diligent in housework....

In this way, this lady really has a great background.

"Our mother and son are here to escape, I don't want my son to be murdered by them, so I fled here, but my body is not as good as day by day...", the eldest lady sighed.

"The eldest lady and Huan'er are from a big family." , Chu Yu's tone was very affirmative.

The eldest lady paused and said, "Miss Yu is really smart. ”

Chu Yu smiled and said nothing, this hundred days deep is a secret poison made by the palace, but in the end, it still circulated among the people.
